Abstract

We demonstrate that the resonant medium with essentially nonlinear field coupling can exhibit specific response when excited by the few-cycle optical pulse. We provide an effective theoretical background that allows relating the type of the field coupling function with the medium oscillators output on the few-cycle pulse-driven excitation. Possible applications of such the optical response are discussed for the controllable generation and shaping of the unipolar video pulses.
